• jQuery Thickbox and Google Maps Extinfowindow

  - by cdonner

  I am trying to place a link into an Extinfowindow that obtains its content through an Ajax call. So, I click on a push pin marker, up pops the Extinfowindow with my ThickBox link in it, and when I inspect the DOM for the entire page at that point, I can see the element correctly showing up with the "thickbox" class. The link looks like this <A class="thickbox" title="" href="http://localhost:1293/Popup.aspx? height=200&width=300&modal=true">Modal Popup</A> However, when I click on it, it does a full refresh and the target page loads in the browser, not in a popup. It seems that when the <A> for the Thickbox control is injected into the DOM after the initial load, jQuery is no longer able to do its magic and intercept the anchor link request. Does anybody have thoughts about how to do this better?

• JQuery Tablesorter memorizeSortOrder widget

  - by echedey lorenzo

  Hi, I've found this code in the internet: $.tablesorter.addWidget({ id: "memorizeSortOrder", format: function(table) { if (!table.config.widgetMemorizeSortOrder.isBinded) { // only bind if not already binded table.config.widgetMemorizeSortOrder.isBinded = true; $("thead th:visible",table).click(function() { var i = $("thead th:visible",table).index(this); $.get(table.config.widgetMemorizeSortOrder.url+i+'|'+table.config.headerList[i].order); }); } // fi } }); Found in: http://www.adspeed.org/2008/10/jquery-extend-tablesorter-plugin.html I would like to memorize the sorting of my ajax tables so on each update (table changes completely so there is no append) it keeps sorted the as it was. Question is.. how can use this? $("#tablediv").load( "table.php", null, function (responseText, textStatus, req) { $("#table").trigger("update"); } ); What changes do I need?

• Design for a machine learning artificial intelligence framework (community wiki)

  - by Lirik

  This is a community wiki which aims to provide a good design for a machine learning/artificial intelligence framework (ML/AI framework). Please contribute to the design of a language-agnostic framework which would allow multiple ML/AI algorithms to be plugged into a single framework which: runs the algorithms with a user-specified data set. facilitates learning, qualification, and classification. allows users to easily plug in new algorithms. can aggregate or create an ensemble of the existing algorithms. can save/load the progress of the algorithm (i.e. save the network and weights of a neural network, save the tree of a decision tree, etc.). What is a good design for this sort of ML/AI framework?

• Display Image over map layer in GeoServer

  - by iririr

  Hi I am newbie when it comes to GeoServer and trying to figure out if there is an easy way to display images on top of map layer. A background: In my application, based on a search criteria, some polygons are drawn on the map. Each polygon has a corresponding image (in TIFF format) that is stored somewhere. I want to load the image on top of the map when the user zooms in to a certain zoom level. I know this can be done using openLayers but since my images are in TIFF format, (openLayers is not able to render TIFF images as far as i know) i have to convert them to .PNG first which would be very slow considering the number of images i have. Hence I was wondering whether it would be possible to create a image layer that would retrieve an image of a certain polygon at a certain zoom level. If so, could anyone point me to an example or give me an idea on whether this is possible. I am using spring 2.5, tomcat 5, java 1.6 and geoserver 2.0 Thanks.

• Cross-domain jQuery using YQL gives robots.txt error

  - by Jens Roland

  On the page http://qxlapps.dk/test.htm I am trying to perform an Ajax load from another domain, qxlapp.dk. I am using James Padolsey's xdomainajax.js plugin from: http://james.padolsey.com/javascript/cross-domain-requests-with-jquery/ When I open my test page, I get no output, but FireBug shows the JSON result, including the error message: "forbidden":"robots.txt for the domain disallows crawling for url: http://qxlapp.dk/projects/dagens_kup/show.php". The robots.txt on the qxlapp.dk domain contains the following: User-agent: Yahoo Pipes 2.0 Allow: / User-agent: * Allow: / So I don't see what the problem is? Shouldn't it pull the page just fine with those settings?

• CommandBinding CanExecute always null

  - by developer

  Hi All, I am using CommandBinding to display visibility of a button. Below is my code <UserControl.CommandBindings> <CommandBinding Command="{x:Static local:AttendeePanel.LaunchAttEditor}" Executed="LaunchAttEditor_Executed" CanExecute="CanCreateProfile"/> </UserControl.CommandBindings> <Button Content="Create Profile" Command="local:LaunchEditor" CommandParameter="{Binding Profile}" Name="BtnCreate"> My problem is that CanExecute method always gets null as parameter even though I am binding the parameter to Profile. Is there a way I can set Data Context? or is this because the canexecute runs before data load?

• manipulate objects outside svg with javascript-function inside the svg

  - by Christian Benke

  Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian

• How to use Win32 SetCursor() with WPF resource and HwndHost

  - by Hank

  We have an HwndHost UIElement in our WPF application which is used to display Direct3d graphics, and the only way I have found to set a cursor for the HwndHost UIElment is to call the Win32 API SetCursor(). All of our cursors are resources in managed assemblies, and I would prefer to not change that, but I have not been able to find a way to load one of these cursors via any Win32 APIs like LoadImage(). Does anybody know how to get a handle(hCursor) to a cursor which is a resource in a managed assembly? Or, is there another way to set a cursor on an HwndHost displaying Direct3D graphics?

• Webbrowser control: auto fill, only works one time, why?

  - by Khou

  The following code loads a page and auto fills in the values. private void button1_Click(object sender, EventArgs e) { //Load page and autofill webBrowser1.Navigate("http://exampledomain.com"); webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(autoFillDetails); // etc...etc.. } private void autoFillDetails(object sender, WebBrowserDocumentCompletedEventArgs e) { // do auto fill values ((WebBrowser)sender).Document.GetElementById("MY_NAME").SetAttribute("value", "theMynamevalue"); // etc...etc... } Autofill only work one time! After the form has been submitted, and you navigate back to the page previous form page (even when you click the button again), it will no longer auto fill the form values! Note: The the "autoFillDetails" code is executed a second time, 3rd time etc, it still would not auto fill the values. why does it only work one time? what am i doing wrong?

• how secure is NSURLConnection over https

  - by drunken_elf

  I've been reading through a number of questions on this site regarding NSURLConnection and https, but most relate to "untrusted" certificates and how to allow them nonetheless. My question is a little more basic. I am building an app for a client who handle online donations, and I would like to load their donation script using an NSLURLRequest and POST the values of credit card details (entered in the app). Does NSURLConnection (when connecting to a https url) ensure the encryption of those details as they are sent to the donation script on my clients server? Sorry if this is a basic question, I just couldn't find a place in the apple docs that guaranteed this.

• Error when using mailto: link in Mobile Safari in app-capable mode

  - by Elisabeth

  I've got a form in a web page with an action that is "mailto:email" (where email is a real email address). When I load this page in Mobile Safari in regular mode (ie, not launched from home screen with app-capable mode), this works fine - after I submit the form, the email app comes up. However, when I'm in app-capable mode and have launched from the home screen (so, no Safari chrome), and submit the form I get the error "URL can't be shown". However, a regular mailto: link (ie, not in a form) does work when in app-capable mode. Has anyone else noticed this? Any workarounds? Are forms disallowed in app-capable mode? Thanks, Elisabeth

• SQL CLR Assembly Error 80131051 when late binding to a registered C# COM .dll

  - by Shanubus

  I must have hit an unusual one, because I can't find any reference to this specific failing anywhere... Scenario: I have a legacy SQL function used to transform(encrypt) data. This function is called from within many stored procedures used by multiple applications. I say this, because the obvious answer of 'just call it from your code' is not really an option (or at least one I'd prefer not explore). The legacy function used sp_OA with an ActiveX dll on SQL2000 to perform its work. The new function is targeted at SQL2008 x64. I am ditching the sp_OA call in favor of CLR assembly; and am getting rid of the ActiveX dll and using a COM+ .dll (3rd party) to perform the same work. This 3rd party COM+ is required to be used based on spec given to me, so can't get rid of this piece either. Problem: After multiple attempts at getting this to work I have eliminated the following approaches 1) Create a Sql Assembly to call the local COM+ directly -- Can't do this as it requires a reference to System.EnterpriseServices. Including this requires that a whole slew of unsupported assemblies be registered which I don't want. The COM+ requires it's methods to be accessed via an Interface, so my attempts at late binding to it directly have not been successful (late binding would allow me to drop the unsupported references). 2) Create a Sql Assembly which references a C# class library that then calls the COM+. -- Same issue as #1; since the referenced dll uses System.EnterpriseServices and will be added as a dependency when referenced in the Sql Assembly, again trying to load all the unsupported libraries 3) Create a Sql Assembly which late binds to an ActiveX COM dll that calls the COM+. -- Worked in my dev environment, but can't go to x64 in production with ActiveX dll's written in VB6 (not to mention I hate backtracking anyway)... again failure... I am now onto an approach that is almost working, with of course one last hangup. I now have -a Sql Assembly that late binds to a C# COM dll, eliminating the need for including System.EnterpriseServices and eliminating the need to reference the C# COM in the SqlAssembly itself. The C# COM does reference System.EnterpriseServices to call the COM+, but since I am late binding to it from the SqlAssembly, I bypass the need for Sql to actually load them as referenced assemblies. Works in debugger.. Works on my dev box when the SqlAssembly dll is referenced in a test console app and called directly Installs to Sql2008 just fine Executing the actual UDF works, but returns no data due to a failure reporting from the late bound dll! So the SqlAssembly is instanciated just fine. It actually fails on it's late binding to the C# COM, which is working from a test console app on the same machine. It appears to be a difference in behavior based on whether called from within the SQL UDF or not. Since it is working on the same box from my console app, I am assuming it's on the SQL side. My steps to install were. --Install the COM+ dll and ensure it can be called successfully (as from with in the console app) --Register the C# COM dll (which calls the COM+) and get it to the GAC (again proofed to be working from console app) --Create my Assymetric Key CREATE ASYMMETRIC KEY SqlCryptoKey FROM EXECUTABLE FILE = 'D:\SqlEx.dll' CREATE LOGIN SqlExLogin FROM ASYMMETRIC KEY SqlExKey GRANT UNSAFE ASSEMBLY TO SqlExLogin GO --Add the assembly CREATE ASSEMBLY SqlEx FROM 'D:\SqlEx.dll' WITH PERMISSION_SET = UNSAFE; GO --Create the function CREATE FUNCTION dbo.f_SqlEx( @clearText [nvarchar](512) ) RETURNS nvarchar(512) WITH EXECUTE AS CALLER AS EXTERNAL NAME SqlEx.[SqlEx.SqlEx].Ex GO With all that done, I can now call my function SELECT dbo.f_SqlEx('test') But get this error in the event log... Retrieving the COM class factory for component with CLSID {F69D6320-5884-323F-936A-7657946604BE} failed due to the following error: 80131051. I can't really provide direct code examples, due to internal security implications; but all the code itself seems to work, I am suspecting perms or something of the like... I just find it odd that I can't find any reference to error 80131051. If someone out there believe some 'indirect' code samples will help, I will be happy to provide. Any assistance is appreciated.

• Video loads but doesn't play with MPMoviePlayerController in iPad

  - by hgpc

  I'm using MPMoviePlayerController to play videos in an iPad app. Everything works well on the iPad simulator. On an actual device, the videos load but don't play, even if I press the play button. I can move the slider and see different frames of the video, but it never plays. I'm using the following code: moviePlayer = [[MPMoviePlayerController alloc] init]; moviePlayer.shouldAutoplay = YES; moviePlayer.contentURL = video.urlVideo; moviePlayer.view.frame = videoPlayerContainer.bounds; moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [videoPlayerContainer addSubview:moviePlayer.view]; moviePlayer.controlStyle = MPMovieControlStyleEmbedded; [moviePlayer play]; Help?

• Embedded Linux or eCos ?

  - by mawg

  One way to look at it - embedded Linux starts with desktop Linux & ditches the parts not needed for embedded systems (is this actually true?), whereas eCos is designed from the ground up for embedded systems. Now, assume an ARM processor, probably ARM 7 - does performance make a difference? Actually, we talking a very low load system, max 500 transactions a day. Any advantages of one over the other (or FreeRTOS, etc)? Stability, maturity, performance, development tools, anything else? All that I can think of is that if I am certain that I will never port to another o/s, then if I go with embedded Linux, I don't need an o/s abstraction layer to allow me to do unit testing on host (desktop Linux box). Any thoughts or comments? Thanks.

• Convert byte array from Oracle RAW to System.Guid?

  - by Cory McCarty

  My app interacts with both Oracle and SQL Server databases using a custom data access layer written in ADO.NET using DataReaders. Right now I'm having a problem with the conversion between GUIDs (which we use for primary keys) and the Oracle RAW datatype. Inserts into oracle are fine (I just use the ToByteArray() method on System.Guid). The problem is converting back to System.Guid when I load records from the database. Currently, I'm using the byte array I get from ADO.NET to pass into the constructor for System.Guid. This appears to be working, but the Guids that appear in the database do not correspond to the Guids I'm generating in this manner. I can't change the database schema or the query (since it's reused for SQL Server). I need code to convert the byte array from Oracle into the correct Guid.

• LWJGL not working

  I'm working on a homework assignment to modify code given by my professor using LightWeight Java Game Library. The problem is that I can't fully load the test code to begin testing modifications. I've linked against the jar file as it says to in the modifications, but I still have one lingering error. The import statement import org.lwjgl.util.glu.*; Cannot be resolved, so I have errors on the following lines, spread throughout the code: textures[0] = GLApp.makeTexture("green.bmp"); GLU.gluPerspective(45.0f, (float)Display.getDisplayMode().getWidth() / (float)Display.getDisplayMode().getHeight(), 0.1f, 100.0f); GLU.gluLookAt(cameraX, cameraY, cameraZ, lookX, lookY, lookZ, 0.0f, 1.0f, 0.0f);` Any ideas on what is going wrong?

• Google Charts Through CURL

  - by swt83

  I have a PHP class that helps me generate URLs for custom charts using Google Chart service. These URLs work fine when I load them in my browser, but I'm trying to pull them using CURL so I can access the charts on secure https websites. Whenever I try and pull a chart via CURL, I get an Error 400 Bad Request. Any idea on how to get around this? Everything I have tried has failed. $url = urldecode($_GET['url']); $session = curl_init($url); // Open the Curl session curl_setopt($session, CURLOPT_HEADER, false); // Don't return HTTP headers curl_setopt($session, CURLOPT_RETURNTRANSFER, true); // Do return the contents of the call $image = curl_exec($session); // Make the call #header("Content-Type: image/png"); // Set the content type appropriately curl_close($session); // And close the session die($image);

• Google Maps Api v3 - getBounds is undefined

  - by Via Lactea

  Hi All, I'm switching from v2 to v3 google maps api and got a problem with gMap.getBounds() function. I need to get the bounds of my map after its initialization. Here is my javascript code: var gMap; $(document).ready( function() { var latlng = new google.maps.LatLng(55.755327, 37.622166); var myOptions = { zoom: 12, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; gMap = new google.maps.Map(document.getElementById("GoogleMapControl"), myOptions); alert(gMap.getBounds()); So now it alerts me that gMap.getBounds() is undefined. I've tryed to get getBounds values in click event and it works fine for me, but I cannot get the same results in load map event. Also getBounds works fine while document is loading in Google Maps API v2, but it fails in V3. Could you please help me to solve this problem?

• Can I override task :environment in test_helper.rb to test rake tasks?

  - by Michael Barton

  I have a series of rake tasks in a Rakefile which I'd like to test as part of my specs etc. Each task is defined in the form: task :do_somthing => :environment do # Do something with the database here end Where the :environment task sets up an ActiveRecord/DataMapper database connection and classes. I'm not using this as part of Rails but I have a series of tests which I like to run as part of BDD. This snippet illustrates how I'm trying to test the rake tasks. def setup @rake = Rake::Application.new Rake.application = @rake load File.dirname(__FILE__) + '/../../tasks/do_something.rake' end should "import data" do @rake["do_something"].invoke assert something_in_the_database end So my request for help - is it possible to over-ride the :environment task in my test_helper.rb file so I my rake testing interacts with the my test database, rather than production? I've tried redefining the task in the helper file, but this doesn't work. Any help for a solution would be great, as I've been stuck on this for the past week.
